Product details
Overview
MCP4011T-503E/MS from Microchip Technology is a volatile 6-bit digital potentiometer in MSOP-8 package, configured as a potentiometer with 50 kΩ nominal resistance, 64-step resolution, and ±0.5 LSb integral nonlinearity at 5.5V. It operates from 1.8V to 5.5V supply, features 75 Ω typical wiper resistance, and supports high-voltage tolerant U/D control up to 12.5V - used for precision gain/offset trimming in industrial sensor signal conditioning circuits.
For engineers reviewing the MCP4011T-503E/MS datasheet, MCP4011T-503E/MS pinout, MCP4011T-503E/MS application, or MCP4011T-503E/MS equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases, and validated alternative options for analog tuning in space-constrained, wide-temperature designs.
Technical Context
The MCP4011T-503E/MS implements a resistor ladder with volatile RAM-based wiper register, controlled exclusively via simple Up/Down (U/D) serial interface with CS enable. Its potentiometer configuration requires external connection of all three terminals (A, W, B), and power-on defaults to mid-scale (0x1F) wiper position.
It supports two operating modes: standard low-voltage U/D toggling (≤1 MHz, 500 ns timing margins) and high-voltage U/D mode (≥8.5 V threshold) for noise-immune control. Resistor characteristics are specified only between 2.7V–5.5V, while device logic remains functional down to 1.8V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Resistance | 50 kΩ ±20% - defines full-scale analog range for voltage divider or rheostat use; matches R-2R ladder design for predictable step sizing. |
| Resolution | 64 taps (6-bit) - provides 15.625 Ω minimum step size across 50 kΩ, enabling fine-grained calibration in sensor front-ends. |
| Wiper Resistance | 75 Ω typical - contributes minimal series error in low-impedance feedback paths; stable over temperature (±125 Ω max at 2.7V). |
| Tempco (Absolute) | 50 ppm/°C (0°C to 70°C typ.) - ensures <±0.3% resistance drift over industrial ambient range, critical for uncalibrated systems. |
| Supply Voltage Range | 1.8V to 5.5V - enables direct interfacing with 1.8V/3.3V/5V microcontrollers without level-shifting; analog performance guaranteed ≥2.7V. |
| Bandwidth (–3 dB) | 200 kHz - determined by 50 kΩ resistance and internal capacitance; suitable for DC–audio frequency adjustment, not RF. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, motor drive, and industrial control environments without derating. |
Pinout & Package
MSOP-8 package (3.0 mm × 3.0 mm, 0.65 mm pitch), thermally enhanced with θJA = 206°C/W. Pin 1 marked with dot; pins arranged in standard MSOP dual-row layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply rail | Accepts 1.8V–5.5V; powers internal logic and resistor array; must be decoupled near pin. |
| VSS | Ground reference | Return path for supply current and analog terminals; shared reference for A/W/B voltage ranges. |
| A | Resistor array end terminal | Connects to high-side of potentiometer; voltage range limited to VSS ≤ VA ≤ VDD. |
| W | Wiper output terminal | Provides adjustable tap point; supports ≤2.5 mA continuous current; low 75 Ω resistance minimizes loading error. |
| B | Resistor array end terminal | Connects to low-side of potentiometer; same voltage and current limits as Terminal A. |
| CS | Chip select input | Active-low enable for U/D interface; high-voltage tolerant (up to 12.5V); includes weak internal pull-up/pull-down (~16 kΩ). |
| U/D | Up/Down direction control | Edge-triggered logic input; rising edge increments wiper, falling edge decrements; HV mode enabled above 8.5V threshold. |
| NC | No-connect | Internally unused; must remain floating or grounded per PCB layout best practices; no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Volatile wiper memory with POR default | Resets to 0x1F (mid-scale) on power-up - eliminates startup uncertainty in closed-loop systems requiring known initial gain. |
| High-voltage tolerant U/D and CS inputs | Operates reliably with 8.5V–12.5V control signals - enables direct connection to 12V PLC I/O or automotive wake-up lines without external translators. |
| Low static current consumption | 1 µA max (serial interface inactive) - extends battery life in portable instrumentation and IoT sensor nodes. |
| Ratiometric tempco of 10 ppm/°C | Minimizes voltage-divider ratio drift over temperature - preserves accuracy in ADC reference scaling and op-amp gain-setting networks. |
| Wide analog operating range | Terminals A/W/B support full VSS-to-VDD swing - allows bidirectional signal routing and AC-coupled applications without clamping diodes. |
Applications
| Industrial Sensor Calibration | Programmable Gain Amplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5160BRJZ-50-R7 | Nonvolatile EEPROM wiper memory; 64-step; 50 kΩ; SOT-23-6 package; SPI interface. | Retains setting after power loss; requires SPI host instead of GPIO-driven U/D; smaller footprint but no NC pin. | Choose when power-cycle retention is mandatory and SPI is available; avoid if U/D simplicity or MSOP thermal performance is required. |
| MCP4017T-503E/MS | Same family, identical pinout and specs, but includes WiperLock™ technology for accidental-write protection. | Enables hardware lock of wiper position during normal operation; requires VIHH pulse to unlock - adds safety in high-vibration environments. | Choose when field reprogramming risk exists (e.g., automotive ECU); otherwise MCP4011T-503E/MS offers identical functionality at lower cost. |
Compared with AD5160BRJZ-50-R7 and MCP4017T-503E/MS, the MCP4011T-503E/MS prioritizes GPIO simplicity and thermal robustness in MSOP-8, trading nonvolatility and write-protection for lower BOM count and proven stability in extended temperature cycling.

FAQ
What is the nominal resistance tolerance and tempco specification for the MCP4011T-503E/MS?
The MCP4011T-503E/MS has a nominal resistance of 50 kΩ with ±20% tolerance (40.0–60.0 kΩ). Its absolute resistance tempco is 50 ppm/°C (typical, 0°C to 70°C), and ratiometric tempco is 10 ppm/°C (MCP4011/13 only, code = 0x1F). These values are measured with VA = VDD and VB = VSS at TA = +25°C.
Can the MCP4011T-503E/MS operate from a 1.8V supply, and what analog performance is guaranteed at that voltage?
Yes, the MCP4011T-503E/MS operates from 1.8V to 5.5V for logic functionality, but resistor characteristics (RAB, INL, DNL) are only specified and guaranteed from 2.7V to 5.5V. At 1.8V, wiper settling time increases and nonlinearity degrades - use 2.7V+ for precision analog applications.
Does the MCP4011T-503E/MS support rheostat configuration, and how is it implemented?
Yes, the MCP4011T-503E/MS supports rheostat mode by leaving either Terminal A or Terminal B unconnected (floating), using only W and the remaining terminal. This configuration is explicitly supported per datasheet Note 1 and validated for all resistance variants including the 50 kΩ MCP4011T-503E/MS.
What is the maximum allowable voltage on the A, W, and B terminals relative to VSS?
The A, W, and B terminals of the MCP4011T-503E/MS tolerate voltages from VSS to VDD + 0.3V. Exceeding this range risks latch-up or permanent damage. For example, with VDD = 5.5V, the maximum terminal voltage is 5.8V referenced to VSS.
How does the MCP4011T-503E/MS handle power-up, and can the default wiper position be customized?
The MCP4011T-503E/MS performs power-on reset (POR) to wiper address 0x1F (mid-scale) by default. Custom POR settings are possible but require factory programming - not user-configurable in-circuit. The device does not retain wiper position across power cycles due to volatile RAM architecture.
